A glass electrode is generally used for this purpose, in which an internal Ag/AgCl electrode is immersed in a 0.10 M HCl solution that is separated from the solution by a very thin glass membrane (part (b) in Figure \(\PageIndex{5}\)). The glass membrane absorbs protons, which affects the measured potential.

The solubility product constant of AgCl is K sp = 1.8 × 10–10 M2. Using the relevant electrode potentials found on the data page, calculate the reduction potential at 298 K of a half-cell formed by: (a) an Ag electrode immersed in a saturated solution of AgCl. Marks 6 The standard electrode potential for Ag+(aq) + e- Ag(s) is E° = +0.80 V.

(b) In a glass electrode, an internal Ag/AgCl electrode is immersed in a 1 M HCl solution that is separated from the sample solution by a very thin glass membrane.
